Abstract

The utility model discloses a structure for reinforcing floor boards or roof boards of building structures. The structure comprises a floor board or a roof board (1) of a building structure, wherein the floor board or the roof board (1) of the building structure is provided with a groove (2), in which a steel bar (3) is embedded. The steel bar (3), with vertical sticks (3-1) at two ends, is door-shaped. The vertical sticks (3-1) at two ends of the steel bar (3) are vertically anchored in the floor board or the roof board (1) of the building structure. Grouting materials (4) for covering the steel bar (3) are filled in the groove (2). The utility model adds negative bending moment steel bars on existing floor boards or roof boards of building structures, effectively solving the problem of board cracking and insufficient bearing capacity. The structure of the utility model not only has the advantages of convenient construction, good endurance and no maintenance, but also the advantages of relatively low manufacture cost, time-saving and labor-saving construction, etc. The utility model is particularly suitable for reinforcing floor/roof boards which are insufficient in negative bending moment or are cracked.

Description

The ruggedized construction of a kind of building structure floor plate or roof panel

Technical field

The utility model relates to the reinforcement means and the structure of a kind of building structure floor plate or roof panel, belongs to the building structure construction technical field.

Background technology

At present, in the building operations concreting, usually, tend to cause the plate face reinforcing bar of building structure floor plate or roof panel to sink, thereby cause bearing capacity not enough and cause the plate face cracking of building structure floor plate or roof panel because the workman stands in operation on the good steel mesh reinforcement of colligation.In the prior art, the common practices that carries out consolidation process at this class cracking is to adopt the reinforcement means of pasting carbon fibre composite, the existing major defect of existing this reinforcement means is, constructional difficulties higher to construction technical requirement, wastes time and energy, but also it is relatively poor even can not use the problem of (as in wet environment) to exist under some environment durability.Therefore the reinforcement means of existing building structure floor plate or roof panel still is not ideal enough.

Summary of the invention

The purpose of this utility model is, provides a kind of easy construction, good endurance, non-maintaining, laborsaving saving time and the building structure floor plate that cost of manufacture is lower or the ruggedized construction of roof panel, to overcome the deficiencies in the prior art.

The utility model is to constitute like this: the ruggedized construction of a kind of building structure floor plate of the present utility model or roof panel is: comprise building structure floor plate or roof panel, on the surface of building structure floor plate or roof panel, be provided with groove, in groove, be embedded with reinforcing bar, reinforcing bar is the door word shape that two ends are provided with montant, and the montant at reinforcing bar two ends vertically is anchored in the plate of building structure floor plate or roof panel, and filling out to irritate in groove has the grouting material that reinforcing bar is covered in.

Above-mentioned reinforcing bar is the band steel by cold roll forming.

In order to reach better consolidation effect, on the surface of building structure floor plate or roof panel, be coated with one deck leveling layer.

Owing to adopted technique scheme, the utility model has increased the plate negative reinforcement on existing building structure floor plate or roof panel, has solved the plate cracking effectively and has carried hypodynamic problem.Therefore, the utility model compared with prior art, the utility model not only has easy construction, good endurance, non-maintaining advantage, but also has advantages such as cost of manufacture is lower, construction is time saving and energy saving.The utility model is specially adapted to the reinforcing of building/roof panel negative bending moment rib deficiency or plate face cracking and uses.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is A-A sectional structure schematic diagram of Fig. 1.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing the utility model is further described.

Embodiment of the present utility model: when existing building structure floor plate or roof panel are reinforced, when particularly existing building/roof panel negative bending moment rib deficiency or plate face cracking being reinforced, adopt method and structure of the present utility model to reinforce, structural representation of the present utility model as depicted in figs. 1 and 2, during enforcement, the reinforcing bar 3 that to reinforce usefulness earlier is bent into the door word shape that two ends have a montant 3-1 respectively, reinforcing bar 3 can adopt existing 10/8 steel bar cold rolling to be shaped to band steel, on building structure floor plate or roof panel 1, produce groove 2 then, during making, the length of groove 2 is preferably striden 1/4 length by the plate of building structure floor plate or roof panel 1 and is determined, the quantity of groove 2 can be determined according to the needs that use, make a groove 2 by the distance at 15~50 centimetres at every interval generally speaking, and make each groove 2 by being arranged mutually parallel, after removing the dust in each groove 2 totally, in each groove 2, put into the reinforcing bar 3 of a door word shape then, and the montant 3-1 at reinforcing bar 3 two ends vertically is anchored in the plate of building structure floor plate or roof panel 1; With mountain sand, quartz sand and cement is raw material and the grouting material of preparing high fluidity as follows: get river sand 40-50 part (also available mountain sand substitutes river sand) and cement 40-50 part by weight, Admixture 1-5 part, by ratio of water to material is 0.14-0.17, water is added the grouting material 4 that can prepare high fluidity after mixing in the raw material; Grouting material 4 with high fluidity is poured in the groove 2 then, can finish strengthening construction through after the maintenance in the usual way after making grouting material 4 groove 2 be filled and led up and the reinforcing bar 3 of door word shape covered in.In order to reach better consolidation effect, also can on the surface of building structure floor plate or roof panel 1, cover one deck with the leveling layer 5 of ordinary concrete material.

Claims (3)

1. the ruggedized construction of building structure floor plate or roof panel, comprise building structure floor plate or roof panel (1), it is characterized in that: on the surface of building structure floor plate or roof panel (1), be provided with groove (2), in groove (2), be embedded with reinforcing bar (3), reinforcing bar (3) is provided with the door word shape of montant (3-1) for two ends, and the montant (3-1) at reinforcing bar (3) two ends vertically is anchored in the plate of building structure floor plate or roof panel (1), and filling out to irritate in groove (2) has the grouting material (4) that reinforcing bar (3) is covered in.
